Question

A sample of carbon dioxide has a pressure of 1.2 atm, a volume of

Answer 1

The answer for the following question is mentioned below.

Therefore no of moles present in the gas are 1.12 moles

Explanation:

Given:

Pressure of gas (P) = 1.2 atm

Volume of a gas (V) = 50.0 liters

Temperature (T) =650 K

To calculate:

no of moles present in the gas (n)

We know;

According to the ideal gas equation;

We know;

P × V = n × R × T

where,

P represents pressure of the gas

V represents volume of the gas

n represents no of the moles of a gas

R represents the universal gas constant  

where the value of R is 0.0821 L atm  mole^{-1}  K^-1

T represents the temperature of the gas

As we have to calculate the no of moles of the gas;

n = $\frac{P*V}{R*T}$

n = \frac{1.2*50.0}{0.0821*650}

n = \frac{60}{53.365}

n = 1.12 moles

Therefore no of moles present in the gas are 1.12 moles
